4.5.3. Setting the cable equalization

Supported cards
Description: You are able to set the cable
equalization with this command. Use this feature
only if there is no picture or only noisy picture is
present. Be careful because too high or too low
amplification levels can result in video signal loss
or quality decay.
The first version of the command (with @SI) will affect only one input while the
second version (@AI) will set the equalization on ALL supported inputs regardless
of the value of the <in> field.
You have to specify the equalization in decibels with one digit precision. The
decimal point must not be written. Zero value means automatic gain control mode.
Example:
Example:
Note: The MX-DVI-HDCP-IB and MX-HDMI-IB cards support at this moment only
the next equalization modes: Automatic, 3dB, 9dB, 25dB, 35dB, 40dB. Any other
setting will be rejected on these cards and will result in no answer.

4.5.4. Get the actual cable equalization value on an input port

You are able to get the actual amplification level with the HDMIIGET command.
Please refer to the 4.5.5.5 section.

4.5.5. Get detailed information about a HDMI input port

The response repeats the number of the input port after the STI string. There are
different blocks present after the equal sign, which are separated by semicolons.
Every block contains different type of information and can be recognized about the
first character. For example, a block started with 'V' is about the video resolution
